2.8 RB20 for the win

to spoil your fun it wont physically fit in the 20, the bores are the wrong size

Car not finished yet

Tune is about 1/4 way done, some nice timing in the cams... So far on a lite tune it's done 310rwkw at 15psi. Look forward to seeing some results on Monday

Now that is nice, very nice for such a low PSI number. Going to love seeing the dyno graphs.

[GTRKat]

I'm very happy with this at such low poundage

Apparently it sounds frigging awesome as well with the cams timed properly. I'm dying to hear it! Also looking forward to seeing some torque results.

Whats the CR? How ported is the head?

As mentioned, thats a great number!

[GTRKat]

LOL now you're asking questions I have nfi about! Haha will ask about CR when I pick it up.

I have no idea specifics of head porting, left that also to the guys in the know. I just know that Greg spent A LOT of time on the head and he did some bench flow test type thing on it when it was done and was extremely happy with the results.

welcome to the stroker club! big kw at low boost. my 26/30 without cam timing and stock everything made 268 rwkw @ 10 psi so prob similar to yours. haven't done final tune on mine yet.

[N1GTR]

Ok cool that would be good!

Definatly sounds like it flows well. For reference mine had a 100% stock head except springs, on 21psi did 355kw atw with a 3L bottom. The on boost acceleration was just manic, id expect yours to be the same with the 2.8 kit. Now with cams, cam gears and porting id expect to see above 400 kw atw on the same boost on my r32. Regardless of that though the single is out and GTRS's are on, will run to 2 bar i think

[GTRKat]

Before all this started I wanted to be able to run 300awkw all day every day on an awesome strong reliable engine and well on track for that.

Should be able to push for 350awkw but only limitation for me is turbos as for going higher. I think for a while I'll be happy with this! Nice streetable power

I'm getting all excited again!!!!!

hey kat....you should get a single highmount....a really big one

lol im even excited to see what the results are

You'll have a weapon on your hands by the end of this, no doubt about it

I f**king hope so!

[a20089]

Ahh... I'm getting excited waiting for this dyno graph.

Realistically at 15 PSI with the stroker it probably doesn't have that much more to give on those small turbo's, maybe 340kw max? but the response should be awesome.

[GTRKat]

Well turns out the intercooler has let us down a little (damn stocker!). So we can't put the level of boost that we wanted.

Ended up making 320rwkw at 15psi yesterday. So best we're gonna have until the stoopid cooler is swapped out is 331rwkw. Goes like a frigging rocket though, it's hard not to squeal the wheels when I take off

VERY VERY happy with the results, totally different car to drive and the cams sound f**king amazing!

[Swiper the Fox]

it's hard not to squeal the wheels when I take off

taking off is one thing...chirping 2nd is another

LOL I'm trying to AVOID attention!!!

[Swiper the Fox]

Kat most of the 400kw+ Racepace circuit GTR's use stock intercoolers....including their 460KW+ RB29 monster.

just a thought.

[GTRKat]

Interesting to hear.... But my mechanic tells me it must go, I also figure it's 20 years old now and a big front mount is going to look much better than mesh behind my front bar

[N1GTR]

Interesting on the cooler, are you sure its a stocker?

I did 355 on the stock one

ARC do a very nice direct replacement cooler

[Gus-]

i think reece has a ARC one...he said it fits perfectly back into the stock position...no need to modify the bar.
